My question involves criminal law for the state of: Maryland
My Girlfriend and I got into a pointless argument that became violent, she was drinking, so I did not let her leave the house, she became frustrated and started hitting and kicking me, which soon became throwing things at me. I was trying to hold her down and keep her off of me, and she then got free, grabbed a frying pan and hit me with it on the head. I had threatened to call the cops on her a few times, and since she was not backing down, I went ahead and made the call. She ran off, cops found her and took her in, and came to the house to see the evidence of the fight, broken ceramic pot, things thrown around and a rock that she dropped on the floor after kicking in the back door of the house. No damage was done besides a few broken things in the kitchen, and a dented frying pan. I was fine, my nose hurt from getting hit by a pot that was thrown at me, but no mark on my head. The cops reported that she hit me with the pot and the pan on my head, and that there was redness to my face, and a bump on my head. I had a sunburn from being outside all day, and there was no bump on my head, nor did I say that to the officer. After the fight things cooled down and we both came to realize we took it way too far. My girlfriend is being charged of second degree assault, by the state. They did not ask me if I wanted to press charges. I don't want her to go to jail or have to pay a fine that neither of us can afford. I was not seriously hurt besides a bump on my nose. I had called the cops because I didn't want her leaving drunk, and I didn't want to hurt her trying to keep her from driving.
I have no idea how the system works, neither of us have ever been in any trouble before. The police have not contacted me to ask for anything, they just gave my girlfriend a court date. We can't afford a lawyer, and we are worried that without one, she will end up in jail or paying hefty fines. Any advice would be greatly appreciated. Thank you.
